sql读取 所有表、结构 描述
需要：读取库里面所有 表、以及表描述、 列、列描述

--后续 ：记录sql管理维护
场景1：查看所有的表名称(很多时候 不知道表，也不知道表叫什么名称，只记得备注)。
vw_tableDes
create view [dbo].[vw_TableDes]
as
select TableCode=object_name(major_id)
,TableName=cast([value] as nvarchar(100))
from sys.extended_properties
where minor_id=0
要求在建表的时候 需要维护扩展属性：
场景2：有查看所有表，就有查看字段
这里以GGUser为测试 (只备注了name)
